WISCONSIN, A CORPORATION OF WISCONSIN" PAPER WINDING APPARATUS This invention relates to paper winding apparatus and more es eciall to means anc mechanism associated t ierewith for the purpose of ejecting a reel of paper from the winding apparatus and discharging the same onto a receiving surface with a minim um of manual efi'ort.

The tendency in modern paper making practice toward wider machines, often as Wide as 20 feet and upward, has introduced new problems in the handling of the full wound reels of paper as they come from the machine and as they are re-formed on the paper winding apparatus, or rewinder as it 1s more commonly called. Such large reels of paper are necessarily very heavy and cumbersome to handle by the older methods, which all involve considerable manual labor. Furthermore, the handling of lar e rolls by the methods that have hitherto been commonly in practice, would put a considerable strain upon the core-shaft upon whiclrthe paper is wound and might easily result 1n a permanent distortion 0 the shaft.

It is therefore an object of this invention to provide a paper Winding apparatus in which means and mechanism are provided for automatically effecting movement of the wound or partially wound reel of paper fromits normal position in the winding apparatus onto a receiving surface.

It is a further object of this invention to provide an ejecting and discharging mechanism and means for properly coordinating said mechanism to effectuate the removal of a reel of paper from a winding apparatus in a substantially automatic manner.

Other and furthenimportant objects of this invention will become apparent from the disclosures in the specification and the ac- Y companying drawings.

This invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 1 is a side elevational view of a paper winding apparatus embodying the means and mechanism of this invention;

Figure 2 is a similar side elevational view Figure 6 is a fragmentary side elevational view of a modified form of reel handling mechanism.

As shown on the drawings:

The reference numeral 1 indicates a. supporting frame of a paper winding apparatus, commonly used in connect-ion with a paper machine to rewind and slit the parent rolls of paper as they come from the machine into rolls of the required length and diameter. My invention is, however, equally applicable to a paratus or machines for winding any kind 0 web material, either in conjunction with another machine for making the web or as a separate operation.

The winding apparatus here shown includes an adjustable web guiding roll 2 mounted upon the rear of the sup orting frame 1, a slitting mechanism 3, tiirough which a web of paper 4 is adapted to be threaded and a palr of under drums 5 and 6 journalled in bearing brackets 7 and 8, respectively, secured to a portion of the frame 1. The web of paper 4 in its course through the winding ap aratus passes under the winding drum 5 an is wound upon a core or lu-- -rality of cores 9 mounted upon a win ing shaft 10, said winding shaft 10 being supported in the usual manner at its ends in quickly releasable bearin clamps 11.

Each of said bearing camps 11 comprises a lower section 12 hinged as at 13 and an upper stationary section including a spring pressed pawl or dog 14 for engaging a lug formed on said lower hinged sectlon 12.

Said bearing clamps 11 are formed with rearward extensions 15 adapted to slide in vertical guideways 16 formedon the front faces of upstanding side members 17 of the frame 1. Mechanism, including chains 18 secured to each of the bearing clamps '11 and passing over pulleys 19 mounted on the top of said upstanding portion 17, together with hand wheels 20 connected to said pulleys 19 by means of chains 21, serve to raise and lower said bearing clamps 11 and to automaticall take care of the increasing diameter of t e reel 22 during the winding operation. Thismechanism forms a part of standard winding apparatus and is not believed to require further explanation.

It will be understood that a suitable mechanism (not shown) may be used to drive the under-drums 5 and 6, both of these drums being driven in the same direction to wind the web of paper by surface contact upon the shaft 10. Up to this point, the winding apparatus described embodies no novel features over the standard types of rewinders in common use.

My invention, however, includes an ejecting mechanism, indicated as a whole by the re e rence numeral 23, and a-reel rece ving and discharging cradle 24 operatively-associated with said ejecting mechanism and synchronized therewith. By means of these mechanisms, as will later be'explained, the wound or partially wound roll of paper may be automatically rolled over the crown of the under-drum 6 and discharged upon a floor or other receivingsurface 25.

The ejecting mechanism 23 comprises a shaft 26 journaled in the frame 1 as at, 27 (Figure 3) beneath the under'drums 5 and 6 and paral el thereto in equally spaced relation to their respective axes. An arcuate or bent lever arm 28 is ke ed to said shaft 26 at each endthereof insi e of the frame memher 1. In normal position, as illustrated in Figure 1, each of said lever arms 28 comprises a portion 29 extending horizontally and rearwardly and an inte ral end portion 30 extending vertically with its free end slightly above and to the rear of the crown of the under drum 5. A roll 31 is suitably journalled at its ends in said free ends of the levers 28. In normal position, said roll 31 lies behind the reel of paper 22 and out of con tact therewith but, as will later be explained, may be brought into contact with said reel 22 to serve to e]ect said reel from its normal position upon the under drums 5 and 6 The cradle, indicated as a whole by the reference numeral 24, includes a plurality of cradle arms 32, the number of said cradle arms 32 depending upon the width of the winding apparatus, said cradle arms 32 being keyed or otherwise secured to a shaft 33 extending throu h the side of the frame 1 and journalled t erein as at 34.

Each of said cradle arms 32 is formed with a plane receiving surface35 and a forwardly extending arcuate reel discharging surface 36, the reel 22 being shown in dotted lines in,its discharge position in Fig. 1, When the) cradle arms 32 are in reel receiving position (shown in full lines in Fig. 2) the plane receiving surfaces 35 bridge the gap between said cradle arms 32 and the under drum 6, guard plates 37 forming extensions of the plane receiving surfaces 35 for this purpose.

Beneath each of the guard plates 37, there is formed on the rear side of each of the cradle arms 32 a semicylindrica'l socket 39 for receiving an extra winding shaft 40 (Fig. 1).

On the extended ends 41 of the shaft 33 are mounted dependent arms 42, lying outside of the side members of the frame 1 and provided with rearwardly directed arcuate cam surfaces 43. lVith each of said dependent arms 42 is associated a cradle actuating arm 44, keyed to an end of the shaft 26 and provided at its free end with a roller adapted to contact with and follow over the cam surface 43. The cam surfaces 43 are of such length and curvature that when the winding apparatus is in operation, winding up a reel of paper 22 (Fig. 1), the rollers 45 lie beyond said cam surfaces 43 against plane surfaces the cradle 24 is in reel discharge position with the cradle arms 32 resting upon the floor or other receiving surface 25 and the ejector mechanism 23 is out of contact with the reel 22. On the other hand, when the cradle mechanism 24 is in reel receiving position (Fig. 2), the rollers 45 of the cradle actuating arms 44 contact the lower portions of the cam surfaces 43 to bring the cradle arms 32 into supported position with the guard plates 37 bridging the gap to the forward underdrum 6.

Suitable driving mechanism for rotating the shaft. 26 to operate the ejecting and receiving mechanisms 23 and 24 respectively, are shown in Figs. 4 and 5 for mounting on the back or drive side of the machine. As illustrated-in Fig. 4, an arm 46 is keyed at one end to the extended end of the shaft 26, said arm being provided at its free end with a segment gear 47. Said segment gear 47 is adapted to mesh with a pinion gear 48 mounted upon a shaft 49 driven through a gear andworm reducing mechanism, indicated as a whole by the reference numeral 50, from a motor 51. 'A friction safety device 52 is preferably associated with the drive of the worm shaft 53 in order to prevent damage to the driving mechanism due to careless operation.

As illustrated in Fig. 5, the driving mechanism may comprise a pneumatically, or hydraulically, operated piston 54, reciprocally mounted within a cylinder 55 and connected to the shaft 26 by means of a lever arm 56 and a. piston rod 57, said arm 56 and rod 57 being pivotally connected as at 58.- Said cylinder 55 is pivotally mounted upon a pin 66 from a supporting structure 67. Either of these mechanisms described, or other suitable mechanisms, may be operated in an obvious manner to drive the ejecting and roll receiving mechanism of my invention.

In Fig. 6 is shown a slightly modified form of cradle 59 adapted to discharge a reel 60 upon a table 61 or other raised receiving platform. In this modified .form, the cradle arms 62 are formed with upper plane surfaces 63 without the arcuate shaped extremities described above. The cradle arms 62 are shown in full lines in Fi 6 in their normal inoperative position an in dotted lines in their reel receivin position, the operation of said cradles '59 being otherwise the same as previously described, except for the change in the curvature of the cam surfaces 64 rendered necessary by the modified form of cradle 59.

The operation of the ejector roll and cradle mechanisms will be best understood by reference to Figures 1 and 2. After the reel of paper 22 has grown to full size and/or is ready to be discharged from its winding position A (Fig. 2), the motor 51 or hydraulically (or pneumatically) operated piston 54, as the case may be. is started up to move the ejector roll 31 into its position in contact throughout" its full length with the reel 22 to move said reel 22 up onto the crown of the under-drum 6 into position B (Fig. 2). Upon continued movement of. the ejector roll 31, said reel 22 rolls over the crown of said underdrum 6 into position C.

The movement of the cradle mechanism 24 is so synchronized with the movement of the ejector mechanism 23 as to bring the cradle arms 32 into the full line position shown in Fig. 2 by thetime the reel 22 reaches the position B. The rollers 45 are now moving downwardly over the curved cam surfaces 43 without efiectingfurther movementof the cradle mechanism 24 during the continued movement of the ejector mechanism, but movement of the ejector roll 31 is continuous until the reel 22 passes through position C, after which said reel is caused by gravity to roll over the guard plates 37 onto the reel receiving surfaces 35 and ultimately into the arcuate shaped reel discharge surfaces 36 of said cradle arms 32, as indicated by position D in Fig. 2.

The driving mechanism is then reversed to cause the cradle actuating arms 44: to move upwardly, with the rollers 45 moving up over the cam surfaces 43 until they are entirely off of said cam surfaces onto the plane surfaces 65. During this reverse movement of the actuating'arms 44, the cradle arms 32 are gradually lowered into the position shown in Fig. 1, with the reel 22 in position E rea-ly for discharge onto) the receiving surface or floor 25. At the same time the ejector mechanism 23 moves into its rearward, inoperative position (Figure 1). c

It will be apparent that the reel handling mechanism above described is adapted to handle partially .wound or fully wound reels with a minimum of effort and manual labor on the part of theoperator.
